The article is a little vague on details. Thanks. I did not see any discussion of the application that compares the two encrypted objects. Assuming the application has to decrypt it (or there would be no point in sending the secret-key to the other party), what prevents the application developer from writing out the plaintext once decrypted? Would it not have been simpler to just send out the database with message-digests of the names? All one party would have to do is indicate the layout of the plaintext and the digest algorithm. The other party would then digest their own database and compare digested records. There would be no need to send out secret-keys and no possibility of someone writing out plaintext when comparing decrypted objects. Am I missing something?
